- the closing filtering device for a bottle containing a liquid in accordance with the present invention comprises the stopper configured in accordance with the present invention, the pouring insert with the pouring openings said pouring insert comprising additionally the cross partition that adjoins to the pouring insert by means of the radial ribs with the pouring openings being disposed therebetween, said closing filtering device also comprising the sealing element of said pouring insert.
- the assembly for closing a bottle containing a liquid which is characterized by the presence of the bottleneck of the bottle containing the liquid with the closing filtering device fixed thereat, in accordance with the present invention, wherein the pouring insert comprises additionally the air duct, which adjoins, on its inlet side, to the pouring insert with the outlet side of the air duct being inserted, in a backlash-free manner, into the central opening of the stopper being, in accordance with the present invention, in fluid communication with the air duct tube of the stopper.
- the assembly for closing a bottle containing a liquid which is characterized by the presence of the bottleneck of the bottle containing the liquid with the closing filtering device fixed thereat, in accordance with the present invention, wherein the pouring insert comprises additionally the cross partition that adjoins to the pouring insert by means of the radial ribs with the pouring openings being disposed therebetween.
- the inventors have found that the air duct tube being is in fluid communication with the central opening of the stopper and that the filtering openings are disposed on the lower part of the stopper makes it possible to increase the area of the filtering openings, to simplify the design of manufacturing the parts of the closing filtering device, as well as makes it possible to simplify the assembly of the closing filtering device.
- the air duct tube being in fluid communication with the central opening of the stopper enables the air duct tube to be made as a single part with the stopper this making it possible to reduce the cost of manufacture of the stopper and to simplify the process thereof.
- the stopper with the air duct tube is fabricated, for example, of polyethylene, whilst the pouring insert is manufactured, for example, of polycarbonate. This also makes it possible to speed up and simplify the production operation to assembly the closing filtering device.
- the probability of the disconnection of the pouring insert from the stopper during the transportation of the assembled closing filtering device to a filling line is decreased. Since the outlet side of the air duct of the pouring insert is fastened, in a backlash-free manner, in the central opening of the stopper, this makes it possible to fix the outlet side of the air duct of the pouring insert and to reduce thereby vibrations that are transferred from the air duct to the elements of connection of the pouring insert and the stopper.
- the length of the air duct of the pouring insert is shortened materially this making it possible to reduce a load onto the elements of connection of the stopper to the pouring insert, to reduce the consumption of expensive material, of which the pouring insert is usually made, for example, polycarbonate, as well as makes it possible to reduce rejects when manufacturing the pouring insert with the air duct.
- the shortening of the length of the air duct of the pouring insert when using the present invention reduces also a production defect that may occur during the transportation of the pouring insert manufactured to assembly facilities - the defect caused by that the transportation and positioning of the pouring insert results in that a stress is applied to the air duct, which stress is transferred to the longitudinal ribs that connect the air duct to the pouring insert and may lead to cracks, while if a shorter air duct is used, said loads are reduced this, accordingly, resulting in the reduction of production defect.
- the end wall is provided on the outlet side of the air duct tube of the stopper.
- Said end wall comprises the outlet opening this making it possible to regulate both shape and diameter of the outlet opening of the air duct tube of the stopper over a wide range.
- the location of the filtering openings between the longitudinal ribs makes it possible to increase the total filtering surface of the stopper.
- the presence of the support band, to which the longitudinal ribs of the stopper adjoin increases the reliability of the stopper design this making it possible to reduce the wall thickness of the stopper in the upper part thereof from 1 mm down to 0.7 mm while, in the area of disposition of the filtering openings, the reduction of the thickness of the lower part of the stopper from 1 mm down to 0.3 mm is possible with the preservation of its operational (strength) characteristics this making it possible to reduce material consumption for manufacturing the stopper this also being an advantage of the present invention.
- the present invention makes it possible to reduce significantly the time of its production and assembly because, during the manufacture of the stopper, the filtering openings of the lower cone part of the stopper are made at once.
- the necessity of manufacturing the filtering plate and installing it during assembly is eliminated as compared with the prior art.
- the present invention makes it possible to reduce the number of parts this leading to a reduction in the technological operations for assembling the closing filtering device this also being an advantage of the present invention.
- the alignment of the parts is simplified in the assembly process this also being an advantage of the present invention.
- said filtering openings are provided in the truncated cone, this makes it possible to use a various total flow cross-section of the filtering openings of the stopper this ensuring an uneven flow of the filtered liquid along the length of the lower part of the stopper this making it possible to stabilize the air flow and ensuring an air entry into the stopper cavity through the pouring openings of the pouring insert while the air duct tube being in fluid communication with the central opening of the stopper ensures air supply from the stopper cavity through the air duct tube to the cavity of the bottle containing the liquid.
- the air movement velocity in the pass-through openings formed by the cross partition is increased this creating an additional aerodynamic lock preventing any unfiltered liquid from flowing out into throughout air duct of the pouring insert.
- the presence of the cross partition also improves the mating of the inner surface of the support band of the central opening of the stopper with the outer surface of the air duct of the pouring insert and retains its properties under temperature fluctuations, since the stopper and the air duct of the pouring insert are made of different materials this also being an advantage of the present invention.
- the inventors of the present invention have found that the presence of the cross partition increases the quality of the manufacture of the pouring insert and reduces the probability of formation of caverns on its surface, the presence of which worsens the tightness of the pouring insert in the area of its adjacency to the stopper.

Abstract
Description
- The invention relates to closing filtering devices for a bottle containing a liquid. The invention claimed is intended to separate solid particles from the liquid that is poured out of the bottle.
- Various alcoholic and low-alcohol beverages, such as vodka, whiskey, wine, etc., which are bottled in glass food bottles, are widely used in the marketplace. In order to distinguish the product and quickly identify it among other similar products, solid contents are added to the bottle, for example, pepper, wheat ears, etc. are added to vodkas, giving or quickly indicating to the buyer the consumer properties of the internal contents of the bottle containing a liquid.
- In the course of transportation and storage of stoppered bottles containing a liquid, the solid contents may break down to form solid particles or impurities, which are distributed in the liquid and which may be poured out of the bottle with the liquid. The presence of solids poured out of the bottle with the liquid is undesirable, because the ultimate consumer will try, on a subconscious level, to separate the solids from the liquid, despite their small size, and, furthermore, due to the presence of solids, may relate with caution to the consumer properties of the liquid and advance unreasonably judgment of its low quality. Cereal plants (lat. Gramineae) form solid particles in the form of awns (lat. arista), which may stick to the throat and cause its irritation, which is also an undesirable phenomenon.
- Accordingly, what is needed is to separate small solid impurities from a liquid that is poured out of a bottle.
-
- The most similar to the closing filtering device for a bottle containing a liquid in accordance with the present invention is a closing filtering device for a bottle containing a liquid disclosed in document No.
PCT/IB2018/051426 , that comprises a stopper, a pouring insert with pouring openings, the pouring insert being connected to the stopper, the pouring insert comprising additionally an air duct that adjoins the pouring insert on the inlet side, the outlet side of the air duct going from the central opening of the stopper, and, furthermore, said closing filtering device comprising a sealing element of the pouring insert. - The stopper of the prior art closing filtering device for a bottle containing a liquid, which is placed in the pouring opening of the neck of said bottle containing the liquid, comprises sealing protrusions provided on the outer surface of said stopper in the upper part thereof, with the lower part of the stopper being made narrowed in the form of a truncated cone, in the upper smaller base whereof a central opening being provided and the stopper also comprising longitudinal ribs.
- The assembly for closing a bottle containing a liquid is formed as a result of the fixation, at the bottleneck, of the closing filtering device for a bottle containing a liquid, said device comprising the stopper fixed in a pouring opening of the bottle neck of said bottle by means of the sealing protrusions provided on the outer surface of said stopper in the upper part thereof, with the lower part of the stopper plug being made narrowed in the form of a truncated cone, in the upper smaller base whereof a central opening being provided, the stopper also containing the longitudinal ribs and the air duct, the pouring insert with the pouring openings adjoining to the outlet side of said air duct, the pouring insert being connected to the stopper with the air duct going from the central opening of the stopper on the outlet side of said air duct, said closing filtering device comprising also filtering openings and the sealing element of the pouring insert.
- The design feature of the prior art technical solution is that it comprises, as a separate part, a lamellar filtering insert, installed on the longitudinal ribs of the stopper across its cavity. The lamellar filtering insert is provided with pass-through openings, and the lamellar filter insert is also provided with a mesh with filtering openings for separating solid impurities from liquid which is poured from the bottle. The lamellar insert is pressed by the pouring insert against the longitudinal ribs this ensuring that the lamellar insert is securely seated in the stopper cavity.
- The sealing element of the pouring insert is in the form of a cover located on the pouring insert and covering the pouring openings and the outlet opening of the air duct.
- The prior art technical solution functions as follows: For pouring out the liquid from the cavity of the bottle, it is tilted and the liquid comes through the central opening of the stopper in its cavity. From the stopper cavity, the liquid passes through the filtering openings of the mesh of the plate insert, as a result of which the liquid is filtered and the filtered liquid, through the holes of the lamellar insert, enters the pouring insert, wherefrom the filtered liquid is poured out of the bottle through its pouring opening.
- While pouring the liquid out of the bottle, a vacuum is created in the bottle cavity and, as a result, the ambient atmospheric air flows through the air duct into the bottle cavity.
- The disadvantages of the prior art technical solution include, among others:
- A small area of the filtering openings of the lamellar filtering insert,
- High costs associated with the manufacture of the lamellar filtering insert with the filtering openings, which are formed by a mesh;
- The presence of additional process operations to install the lamellar filtering insert into the stopper cavity during the assembly of the closing filtering device;
- A low reliability of the closing filtering device design due to the fact that during the transportation of the assembled closing filtering device to a filling line, there may be a fall-out of the pouring insert from the stopper cavity, since the air duct is essentially a lever whose the outlet side whereof is not fixed in the stopper cavity this resulting in a load onto the joint between the pouring insert and the stopper; and
- The possibility of unfiltered liquid "leaking" through the outlet opening of the air duct.
- In view of the above-mentioned disadvantages of the prior art, it is an object of the present invention to improve the design reliability of the closing filtering devices for a bottle containing a liquid, the stopper thereof, and the assembly for closing the bottle containing a liquid.
- Furthermore, it is an object of the present invention to simplify both design and assembly of the closing filtering device for a bottle containing a liquid.

- The inventors have found that the air duct tube being is in fluid communication with the central opening of the stopper and that the filtering openings are disposed on the lower part of the stopper makes it possible to increase the area of the filtering openings, to simplify the design of manufacturing the parts of the closing filtering device, as well as makes it possible to simplify the assembly of the closing filtering device.
- The air duct tube being in fluid communication with the central opening of the stopper enables the air duct tube to be made as a single part with the stopper this making it possible to reduce the cost of manufacture of the stopper and to simplify the process thereof. The stopper with the air duct tube is fabricated, for example, of polyethylene, whilst the pouring insert is manufactured, for example, of polycarbonate.

It should be also noted that the shortening of the length of the air duct of the pouring insert when using the present invention reduces also a production defect that may occur during the transportation of the pouring insert manufactured to assembly facilities - the defect caused by that the transportation and positioning of the pouring insert results in that a stress is applied to the air duct, which stress is transferred to the longitudinal ribs that connect the air duct to the pouring insert and may lead to cracks, while if a shorter air duct is used, said loads are reduced this, accordingly, resulting in the reduction of production defect.
- According to another embodiment of the present invention, the end wall is provided on the outlet side of the air duct tube of the stopper. Said end wall comprises the outlet opening this making it possible to regulate both shape and diameter of the outlet opening of the air duct tube of the stopper over a wide range. It should be noted separately that making the outlet opening of the air duct tube in the form of a confuser expanding from the central opening of the stopper makes it possible to increase an air movement velocity and an air flow density in its narrowest part, while, for a liquid, a flow resistance is increased due to the widening of the confuser of the outlet opening from the central opening of the stopper, and this leads to a smaller tilt angle of the bottle containing a liquid for a possible "leaking" of an unfiltered liquid out of the bottle cavity into the air duct tube of the stopper through the outlet opening of the air duct tube of the stopper this also being an advantage of the present invention.
- The location of the filtering openings between the longitudinal ribs makes it possible to increase the total filtering surface of the stopper.
- Moreover, the presence of the support band, to which the longitudinal ribs of the stopper adjoin, increases the reliability of the stopper design this making it possible to reduce the wall thickness of the stopper in the upper part thereof from 1 mm down to 0.7 mm while, in the area of disposition of the filtering openings, the reduction of the thickness of the lower part of the stopper from 1 mm down to 0.3 mm is possible with the preservation of its operational (strength) characteristics this making it possible to reduce material consumption for manufacturing the stopper this also being an advantage of the present invention.
- The present invention makes it possible to reduce significantly the time of its production and assembly because, during the manufacture of the stopper, the filtering openings of the lower cone part of the stopper are made at once. The necessity of manufacturing the filtering plate and installing it during assembly is eliminated as compared with the prior art. Also, the present invention makes it possible to reduce the number of parts this leading to a reduction in the technological operations for assembling the closing filtering device this also being an advantage of the present invention. It should be also noted that the alignment of the parts (the stopper, the pouring insert) is simplified in the assembly process this also being an advantage of the present invention.
- The employment of the cross partition in the pouring insert, which partition adjoins to the pouring insert through the radial ribs, makes it possible to align and stabilize the flow of the liquid being poured out of the bottle through the filtering openings of the stopper provided on the side surface of the truncated cone. Because said filtering openings are provided in the truncated cone, this makes it possible to use a various total flow cross-section of the filtering openings of the stopper this ensuring an uneven flow of the filtered liquid along the length of the lower part of the stopper this making it possible to stabilize the air flow and ensuring an air entry into the stopper cavity through the pouring openings of the pouring insert while the air duct tube being in fluid communication with the central opening of the stopper ensures air supply from the stopper cavity through the air duct tube to the cavity of the bottle containing the liquid.
- An additional presence of the air duct in the pouring insert, which air duct is inserted, on the outlet side thereof, into the central opening of the stopper in a backlash-free manner, makes it possible to ensure a fuller air supply to the bottle cavity when the liquid is poured out through the bottleneck. The presence of the cross partition comprising the pass-through openings in the outlet opening of the air duct also reduces the possibility of unfiltered liquid leaking from the air duct tube to the air duct of the pouring insert.
- The location of the longitudinal ribs within the stopper cavity, which ribs adjoin to the support band, performs also the function of air duct guides into the central opening of the stopper during its assembly, this reducing rejects during assembly and increasing an assembly rate this also being an advantage of the present invention.
- The presence of a taper on the outer surface of the air duct makes it possible to improve the mating and connection point of the air duct and the central opening this increasing the reliability of fixation of the pouring insert on the stopper.
- It should also be noted that the presence of the pass-through openings and the air duct increases the resistance this leading to a reduction in the probability of unfiltered liquid spilling out through the air duct of the pouring insert.
- The air movement velocity in the pass-through openings formed by the cross partition is increased this creating an additional aerodynamic lock preventing any unfiltered liquid from flowing out into throughout air duct of the pouring insert.
- It should be added separately that the presence of the cross partition also improves the mating of the inner surface of the support band of the central opening of the stopper with the outer surface of the air duct of the pouring insert and retains its properties under temperature fluctuations, since the stopper and the air duct of the pouring insert are made of different materials this also being an advantage of the present invention.
- Also, the inventors of the present invention have found that the presence of the cross partition increases the quality of the manufacture of the pouring insert and reduces the probability of formation of caverns on its surface, the presence of which worsens the tightness of the pouring insert in the area of its adjacency to the stopper. Also, the presence of the cross partition leads to acceleration of the casting process of the pouring insert with the air duct by up to 30% this also being an advantage of the present invention.
- It should also be noted that the provision of the support band in the upper smaller base of the truncated cone of the lower part of the stopper and the adjoining the air duct of the stopper thereto makes it possible to shift the center of gravity of the stopper to the upper smaller base of the truncated cone, which simplifies and accelerates the positioning of the stopper in the automatic assembly machine this also being an advantage of the present invention.
- It should also be noted once again that, in accordance with one embodiment of the present invention, the length of the air duct of the pouring insert does not exceed the height of the cavity of the stopper, and this makes it possible to reduce expenses for expensive polycarbonate, from which the pouring insert is made, which also increases the quality and speed of casting the pouring insert with the air duct, and also reduces the amount of stress caused by the air duct on the radial ribs during the storage and transportation of manufactured pouring inserts with the air duct and this leads to a decrease in their rejects this also being an advantage of the present invention.
- It should also be noted that the inventors have found that the provision of the filtering openings in the lower part of the stopper made in the form of the truncated cone, to the upper smaller base whereof the air duct tube adjoins, makes it possible to produce a pressure difference sufficient to carry air from the cavity of the stopper through the air duct into the bottle cavity, and to provide sufficient head for the liquid poured out of the bottle.

The present invention, however, is not limited to the accepted terms and it should be borne in mind that each such term encompasses all equivalent solutions, which operate in a similar manner and are used to solve the same problems.

The sealingprotrusions 11 are provided on the external surface of thestopper 1 in the upper part thereof (Fig.1 ). Alower part 12 of thestopper 1 is made in the form of the truncated cone (Fig.2 ) with acentral opening 13 being formed in the upper, smaller base whereof (Fig.4 ). Anair duct tube 2 adjoins to asupport band 15 and, in its inlet, is in fluid communication with thecentral opening 13 of thestopper 1. On the outlet side of aair duct tube 2, anend wall 22 is provided, in which anoutlet opening 21 is provided in the form of a confuser (Fig.1 ) expanding from thecentral opening 13 of thestopper 1. - A pouring
insert 3 is located on thestopper 1 and comprisesradial ribs 32 , which, on one side, adjoin to the pouringinsert 3 and, on the other side, adjoin to therapeuticair duct tube 2 on the inlet side thereof with pouringopenings 31 being located betweenradial ribs 32 . The pouringinsert 3 comprises additionally anair duct 33 , which, on its inlet side, adjoins to the pouringinsert 3, while the outlet side of anair duct 33 is inserted, in a backlash-free manner, into thecentral opening 31 of thestopper 1 being in fluid communication withair duct tube 2 of thestopper 1. - The outlet opening of the
air duct 33 of the pouringinsert 3 comprises across partition 34 with pass-throughopenings 35 . - Disposed in the cavity of the
stopper 1 are thelongitudinal ribs 14, which adjoin (seeFig.1 ,Fig. 4 ) to thesupport band 15 , which is provided in the upper, smaller base of the truncated cone of thelower part 12 of thestopper 1. -
Filtering openings 4 are provided on the side surface of the truncated cone of thelower part 12 of thestopper 1. Thefiltering openings 4 have a slit-like shape and are located between adjacent longitudinal ribs 14 (Fig.4 ). - A sealing element of the pouring
insert 3 is made in the form of acover 5, which closes (seals) the pouringopenings 31 and the inlet opening of theair duct 33 of the pouringinsert 3. - The closing filtering device for a bottle containing a liquid in accordance with the first embodiment of this invention is fabricated as follows: First, the
stopper 1 with theair duct tube 2; the pouringinsert 3 with theair duct 33 ; thecover 5, aprotective cap 7 are produced in separate casting molds. Thestopper 1 and thecover 5 are produced, for example, of polyethylene. The pouringinsert 3 with theair duct 33 is made, for example, of polycarbonate. Theprotective cap 7 is fabricated, for example, using a metal drawing method, for example, of aluminum or alloys thereof. - Prior to the assembly, the
protective cap 7 is molded, namely, aninternal collar 71 is molded to retain the closing filtering device assembled in theprotective cap 7 due to the engagement thereof with thecover 5, as well as aperforation line 72 used to separate alower part 73 of theprotective cap 7 is produced. - The closing filtering device is then assembled. For this, the
stopper 1 is connected to the pouringinsert 3, and, as a result thereof, the pouringinsert 3 is fixed on thestopper 1 and the outlet of theair duct 33 is inserted into thecentral opening 13 of thestopper 1. The external surface ofair duct 33 adjoins thesupport band 15 , and the internal cavity of theair duct 33 is in fluid communication with the internal cavity of theair duct tube 2 of thestopper 1. - The
cover 5 is then installed onto the pouringinsert 3. As a result thereof, an assembled closing filtering device is produced (Fig.1, Fig.2 ). - The assembled closing filtering device is ten installed into the
protective cap 7; when doing so, the outer edge of thecover 5 engages with theinternal collar 71 of theprotective cap 7 and, as a result thereof, thecover 5 is fixed on the internal end surface of theprotective cap 7. - As a result, the closing filtering device for a bottle containing a liquid, which device is inserted into the protective cap 7 (
Fig.7 ), is produced. - The assembled closing filtering device (
Fig.7 ) is then delivered (transported) to a filling line where a solid content is placed into the bottle cavity (not shown in the Figures) and a liquid is poured into the bottle cavity through the pouring opening of thebottleneck 6. The closing filtering device is then installed onto thebottleneck 6 and is fixed thereon (Fig.7 ). When doing it, thestopper 1 is disposed in the pouring openings of thebottleneck 6 and is fixed therein by means of the sealingprotrusions 11 . The pouringinsert 3 is fixed on thestopper 1. Athread 74 is then rolled in the upper part of theprotective cap 7, which thread matches amale thread 61 of thebottleneck 6 and a fixinggroove 75 at alower part 73 of theprotective cap 7 is rolled. The fixinggroove 75 engages with anexternal collar 62 of thebottleneck 6. - As a result thereof, the assembly for closing a bottle containing a liquid is formed (
Fig. 8 ). The assembly for closing a bottle containing a liquid in accordance with the first embodiment of the present invention is characterized by the presence of thebottleneck 6, fixed whereon is the closing filtering device, in which, on the side surface of the truncated cone of thelower part 12 of thestopper 1, thefiltering openings 4 are provided while in the upper, smaller base of the truncated cone of thelower part 12 of thestopper 1, thesupport band 15 is provided all the way around thecentral opening 13 . Theair duct tube 2 being, in its inlet, in fluid communication with thecentral opening 13 adjoins thesupport band 15 ; the pouringinsert 3 comprises additionally theair duct 33 , which, on its inlet side, adjoins to the pouringinsert 3, while the outlet side of theair duct 33 in inserted, in a backlash-free manner, into thecentral opening 31 of thestopper 1, which opening being in fluid communication withair duct tube 2 of thestopper 1. The sealing element of the pouringinsert 3 is made in the form of thecover 5. Thecover 5 is fixed by means of theinternal collar 71 on the internal end surface of theprotective cap 7. Thethread 74 of theprotective cap 7 matches amale thread 61 of thebottleneck 6. The fixinggroove 75 is provided in thelower part 73 of theprotective cap 7 and engages with c theexternal collar 62 of thebottleneck 6 this being necessary to separate thelower part 73 of theprotective cap 7 along theperforation line 72 . - The bottle containing the liquid with the closing assembly formed on its
bottleneck 6 is delivered to the ultimate consumer. - In order to open the assembly for closing (
Fig.8 ), the ultimate consumer holds the bottle with one hand, while, with the other hand, holds the upper part theprotective cap 7 of the assembly for closing and starts rotating it counterclockwise and, as a result of that theprotective cap 7 has thethread 74 that mates themale thread 61 provided on the external surface of thebottleneck 6, theprotective cap 7 at thebottleneck 6, is unscrewed this resulting in the separation of the upper part of theprotective cap 7 from itslower part 73 , which stays on the bottleneck 6 (Fig.9 ) and evidences the first opening of the assembly for closing a bottle containing a liquid. Also, in the process of unscrewing theprotective cap 7, he cover 5 is separated from the pouringinsert 3, this resulting in the opening of the pouringopenings 31 and the inlet opening of theair duct 33 . - Then, in order to pour the liquid out of the bottle, the
bottle 6 is tilted and the liquid from the bottle cavity enters thebottleneck 6 and starts flowing through thefiltering openings 4 of thelower part 13 of thestopper 1. As a result of liquid flowing through thefiltering openings 4, solid particles are separated from the liquid and, as a result thereof, the filtered liquid enters the cavity of thestopper 1, where the liquid flow to be poured out is formed. The liquid is then poured out of the cavity of thestopper 1 through the pouringopenings 31 of the pouringinsert 3. - In the course of pouring out the liquid, a lack of pressure (vacuum) is created in the bottle cavity this resulting in that the atmospheric ambient air enters the
air duct 33 of the pouringinsert 3, and, therefrom, said air, through pass-throughopenings 35 of thecross partition 34 , enters theair duct tube 2 of thestopper 1, from which the air enters the bottle cavity through theoutlet opening 21 this resulting in pressure equalization (compensation) this ensuring that the liquid flows out of the bottle cavity. - In the pass-through
openings 35 of thecross partition 34 and in theoutlet opening 21 of theair duct tube 2, an increase in air velocity occurs this preventing an unfiltered liquid from pouring out into theair duct tube 2 or theair duct 33 . - The provision of the
outlet opening 21 in theend wall 22 in the form of a confuser expanding from thecentral opening 13 of thestopper 1 makes it possible to increase a liquid contact area and, accordingly, this resistance reduces the likelihood of a possible leaking of an unfiltered liquid in the cavity of theair duct tube 2 of thestopper 1 through itsoutlet opening 21 . - It should be noted additionally that the pass-through
openings 35 of thecross partition 34 comprise a smaller cross-sectional area as compared to theoutlet opening 21 of theair duct tube 2, and this reduces the likelihood of the flowing of an unfiltered liquid in the cavity of theair duct 33 . -
Fig.10 depicts the second embodiment of the present invention, which differs from the first embodiment of the present invention in that in the area of the outlet opening of theair duct 33 , a cross-sectional narrowing of theair duct tube 33 is provided and, as a result whereof, ashoulder 36 is formed on its outer surface said shoulder resting on thelongitudinal ribs 14 in the area where they adjoin to thesupport band 15 of thecentral opening 13 of thestopper 1. The presence of theshoulder 36 of theair duct 33 makes it possible to install the pouringinsert 3 with an interference fit this reducing the vibration of the outlet side of theair duct 33 . - The sealing element is configured in the form of a sealing
gasket 51 secured on the internal end surface of theprotective cap 7 by means of theinternal collar 71 . The option of gluing the sealinggasket 51 to the internal end surface of theprotective cap 7 is also envisaged. - The sealing

stopper 1, the pouringinsert 3 with the pouringopenings 31 , connected to saidstopper 1, and the sealing element of said pouringinsert 3, configured in the form of the sealinggasket 51 . The pouringinsert 3 comprises additionally theair duct 33 , which, on its inlet side, adjoins to the pouringinsert 3 while the the outlet side of theair duct 33 is inserted, in a backlash-free manner, into thecentral opening 31 of thestopper 1 connected to theair duct tube 2 of thestopper 1. - The third embodiment of the present invention depicted in
Fig.11 differs from the second embodiment in that anelastic insert 8 is secured on the end surface of theprotective cap 7 with a sealing element configured in the form of the sealinggasket 51 being disposed on the end surface of said elastic insert. Theelastic insert 8 comprises afemale thread 81 , which engages with themale thread 61 provided on the external surface of thebottleneck 6. - The sealing
gasket 51 may be secured on the internal end surface of theelastic insert 8 or may be molded by casting a sealing material, for example, PROVALIN® brand, on the internal end surface of the elastic insert. - The closing filtering device in accordance with the third embodiment consists of the following elements: the
stopper 1 with theair duct tube 2, the pouringinsert 3 with theair duct 33 , theelastic insert 8, the sealinggasket 51 and theprotective cap 7. - The fourth embodiment of the present invention depicted in
Fig.12 differs from the second embodiment in that athread 39 , which engages with thefemale thread 52 of thecover 5 is provided on the external surface of the pouringinsert 3. In the lower part of the pouringinsert 3, there is provided askirt 37 withretainers 38 that face inward into the pouringinsert 3 and engage with anexternal collar 62 provided on thebottleneck 6. - The

Fig.15 differs from the fourth embodiment of the present invention in that theskirt 37 of the pouringinsert 3 has an elongated shape and is located in the upper part thereof areretainers 38 that face inward into the pouringinsert 3 and engage with theexternal collar 62 provided on thebottleneck 6. - The sixth embodiment of the present invention depicted in
Fig.14 ,Fig.15 differs from the first embodiment in that the pouringinsert 3 comprises across partition 310 , which, through theradial ribs 32 , adjoins to the pouringinsert 3 with the pouringopenings 31 being disposed between theradial ribs 32 . The inventors have found that the use thestopper 1 in accordance with the present invention, due to the fluid communication between theair duct tube 2 and thecentral opening 13 of thesupport band 15 of thestopper 1 located in the upper, smaller base of the truncated cone of thelower part 12 of thestopper 1 produces a pressure difference sufficient to carry air from the cavity of thestopper 1 into the bottle cavity through theoutlet opening 21 of theair duct tube 2. Since thelower part 12 of thestopper 1 identification configured in the form of the truncated cone, and, In the process of pouring the liquid out of the bottle, it is tilted, all this leads to an uneven passage of the liquid through thefiltering openings 4 and this results in the presence of air in the cavity of thestopper 1, which air enters said cavity through the pouringopenings 31 of the pouringinsert 3. At the same time, the presence of thecross partition 310 contributes to the formation of a liquid flow, which is poured out of the pouringopenings 31 , as well as prevents the liquid from being splashed. - The assembly for closing a bottle containing a liquid (

Said assembly for closing a bottle containing comprises thebottleneck 6 of the bottle, on the pouring opening whereof the closing filtering device is secured, which device comprises thestopper 1, the pouring insert 3 (Fig.14 ) with the pouringopenings 31 , said pouring insert being connected to saidstopper 1, thefiltering openings 4 and the sealing element of the pouringinsert 3 configured in the form of thecover 5. On the side surface of the truncated cone of thelower part 12 of thestopper 1, thefiltering openings 4 are provided while in the upper, smaller base of the truncated cone of thelower part 12 of thestopper 1, thesupport band 15 is provided all the way around thecentral opening 13 of thestopper 1. Theair duct tube 2, which is in fluid communication with thecentral opening 13 of thestopper 1, adjoins to thesupport band 15 . The pouringinsert 3 comprises thecross partition 310 , which adjoins to the pouringinsert 3 through theradial ribs 32 . The pouringopenings 31 are disposed between theradial ribs 32 . - The authors carried out a series of experiments to determine the rate of pouring liquid from a bottle when using the present invention. For this purpose, a 0.5-L glass bottle with a diameter of the bottleneck pouring openings of 20.5 mm was selected. Pre-crushed solid contents were placed in the bottle cavity, and then liquid - 40% vodka - was poured into the bottle cavity. A liquid with a high concentration of fine solids was artificially formed in the bottle cavity.
- In the course of experiments, the first embodiment (
Fig.1 to Fig.9 ) and the sixth embodiment (Fig.14 ,Fig.15 ) of the present invention were used, in which the assemblies for closing (Fig.8 andFig.14 ) were produced. During the experiments, it was found that the liquid pouring out speed did not exceed 50 seconds, which is sufficient and effective condition of using the present invention, while the solid particles were retained by the closing filtering device. - When using the present invention, a developed filtering surface is formed, on which the filtering openings are provided, and making them slit-like simplifies the manufacture of the stopper and increases their throughput capacity. The location of the filtering openings between the longitudinal ribs increases the reliability of the stopper design.
- While various embodiments of the present invention have been described above, it should be understood that they have been presented by way of example only, and not in limitation.
- This description provides information which is necessary and sufficient for a clear understanding of the present invention. Information which is obvious to those skilled in the art and which has not contributed to a better understanding of the essence of the present invention has not been given in this description.
- The term "truncated cone" also refers to cone-like truncated shapes similar to a truncated cone, for example, the presence of kinks on the internal lateral surface of the truncated cone.
- Furthermore, for example, according to the present invention, it is conceivable that the filter filtering device (
Fig. 1 ) may be installed onto the bottleneck without the protective cap. In this case, a protective film (not shown in the figures) is applied to the cover and the bottleneck on the filling line after the closing filtering device has been installed, for example, by means of heat welding. The ultimate consumer tears off this protective film and then removes the cover from the stopper. - The protective cap or the end surface and/or the side surface of the protective cap may also be embossed.
- From 3 to 16 longitudinal ribs may be employed in the stopper.
- The filtering openings may be provided either in parallel or at an angle to the stopper or in various combinations.
- The technical result of the present invention is that the manufacture and service of the closing filtering device, the stopper thereof, and the assembly for closing a bottle containing a liquid are simplified and the reliability thereof is improved.
